Hands-on Learning of Commercial Electrical Wiring Practices for Electrical Engineering Students Through Two-University Cooperative EffortMany Electrical Engineering students go through their entire program of study withoutencountering the basic practices required by the National Electrical Code. When such topics aretaught, they lend themselves strongly to learning by doing; it is difficult to understand without adominant hands-on component in the instruction. Hardware for training is available throughvendors of education products, but these can be quite expensive. There exists a need for apractical, economical alternative. This paper will describe such an alternative developed throughcooperation between two universities, ________ and _________.These trainers consist of two types of units: student units, intended for hands-on wiring practiceand discovery, and a comprehensive “instructor” unit consisting of all of the elements of thestudent units, designed for demonstration and reference. There are four distinct student units toaddress the following common household and commercial wiring tasks: Breaker panel withsecurity light and standard outlet, ground fault circuit interrupter with downstream load, switchedand unswitched outlets, and three way switches. All units are built with standard wood studdingto resemble a real installation. Electrical boxes are properly attached and, for most of them,Romex is run. Tools such as a screwdriver and pliers are provided. An innovative display andstorage system was created for these units. Design for safety to enable the instructor to controlthe progress of each experiment is included. Cost of a complete set of four student units is about$150. From picking up the materials at a lumberyard to finished, assembled product took theauthor about six hours.For teaching a typical section at each of the two participating universities, two complete sets ofstudent units and one instructor unit were built. The instructor teaches the fundamentals ofhousehold and commercial wiring in two or three lessons using the instructor unit as a fullyoperating demonstrator. Then the students work in a classroom/lab environment to wire up eachof the four student units in turn over two or three lessons. Student involvement was enthusiastic;their feedback will be included in the paper’s assessment section.The paper will include descriptions and diagrams sufficient to replicate each unit. The paper willalso contain a discussion and outline of the instruction, sufficient to understand what is beingcovered. The safety design will be explained in detail. After four semesters of use, anassessment of student learning indicates improved proficiency with the concepts and methodsand an enthusiasm to go with it.
